CDMA-2000 1xRTT is a 3G wireless technology based on the CDMA platform. The 1x in 1xRTT refers to 1x the number of 1.25MHz channels. The RTT in 1xRTT stands for Radio Transmission Technology. The CDMA-2000 1xRTT protocol was developed by Qualcomm. CDMA-2000 1xRTT is a CDMA version of the IMT-2000 standard which was developed by …
Attenuation is a reduction in signal strength over distance. Attenuation is a common problem of telecommunication cables that causes a decrease in data speeds on longer cables. Attenuation is also known as “loss” and can be countered by data repeaters and amplifiers. While attenuation is a problem for long cables, short cables do not usually …
Frame Relay is a protocol for transmitting data over a wide area network (WAN). It was designed to use across ISDN interfaces but it is now used over an assortment of other network interfaces. Once one becomes a master of frame relay design and configuration, it is much easier to obtain a strong understanding of …
An MTRJ connector is a type of fiber optic cable that has an endpoint similar to the RJ-45 connector endpoint found in Ethernet connections. MTRJ connectors are designed to snap into the Ethernet port of a computer, modem, or wireless router and provide that computer or network with extremely fast data transfer rates. MTRJ connectors …
MMDS (Multichannel Multipoint Distribution Service) is a broadband wireless point-to-multipoint specification utilizing UHF (Ultra High Frequency) communications. MMDS operates on FCC licensed frequencies. The FCC divided the United States into BTA's (Basic Trading Areas) and auctioned the rights to transmit on the MMDS bands in each of those areas to MMDS service providers. The MMDS …
Data Over Cable Service Interface Specification (DOCSIS) defines the interface standards for cable modems and supporting equipment involved in high speed data transfer and distribution over cable television system networks. It permits additional high-speed data transfer over an existing cable TV system and is widely used by television operators to offer Internet access through an …
RG-58 is a coaxial cable that is used for wiring purposes. A coaxial cable, in general, consists of an inner conductor that is surrounded by a spacer. The coaxial cable is electrically charged and sometimes consists of different uninsulated conductors that remain entangled with one another. The insulating spacer of the cable is further surrounded …
Every packet based network has an MTU (Maximum Transmission Unit) size. The MTU is the size of the largest packet that that network can transmit. Packets larger than the allowable MTU must be divided into smaller packets or fragments to enable them to traverse the network. Network Standard MTU Ethernet 1500 Token Ring 4096 Packet …
